Control circuitry monitors a voltage across the transistor to determine that the transistor is an overvoltage condition if that voltage exceeds a threshold, and monitors a current through the transistor to determine that the transistor is an overcurrent condition if that current exceeds a threshold. If overvoltage is determined, the control circuitry causes the gate driver to pull up the gate drive signal. If overcurrent is determined, the control circuitry causes the gate driver to pull down the gate drive signal. If either overvoltage or overcurrent is present, a pulse width of the gate drive signal is reduced. |

Fibrous electrode with buckle structure, method of manufacturing the same, and supercapacitor including the same
A fibrous electrode includes a carbon nanotube sheet which is coated on an elastic fiber and has a buckle structure. Thus, the fibrous electrode may maintain a fiber shape, may be light and small and may maintain excellent conductivity even when variously deformed. In addition, the fibrous electrode has high elasticity and thus is capable of being variously deformed (e.g., bent or stretched) and of being realized in the form of textile. As a result, the fibrous electrode may be effectively applied to flexible electronic devices such as implantable medical devices, microelectronic devices, Google glasses, smart watches, wearable computers, and smart clothing. Furthermore, a supercapacitor using the fibrous electrode includes flexible materials and thus is not easily damaged by external force such as tension or pressure. As a result, the supercapacitor may be applied to various fields because of its excellent flexibility. |
